Tetra-kis(1,10-phenanthroline)bis-(?-pyridine-2,6-dicarboxyl-ato)(pyridine-2,6-di-carboxyl-ato)dicopper(II)terbium(III) nitrate tetra-hydrate.

Project description:The asymmetric unit of the title compound, [Cu(2)Tb(C(7)H(3)NO(4))(3)(C(12)H(8)N(2))(4)]NO(3)·4H(2)O, consists of one-half of the C(2)-symmetric trinuclear coordination cation, one-half of the C(2)-symmetric nitrate anion and two water mol-ecules. In the coordination cation, the Cu(II) atom is coordinated by four N atoms from two 1,10-phenanthroline ligands and two O atoms from a bridging-chelating carboxyl-ate group of the pyridine-2,6-dicarboxyl-ate anion, completing a distorted N(4)O(2) octa-hedral coordination environment. The Tb(III) atom, located on a twofold rotation axis, is nine-coordinated by three tridentate pyridine-2,6-dicarboxyl-ate anions forming an N(3)O(6) donor set. The intra-molecular Cu?Tb distance of 5.0592?(11)?Å indicates weak inter-actions between the Cu(II) and Tb(III) atoms. The coordination cations, nitrate anions and water mol-ecules are connected via O-H?O hydrogen bonds into layers parallel to the (001) plane. Moreover, there are extensive ?-? stacking inter-actions [centroid-centroid distances = 4.332?(7) and 3.878?(5)?Å] between the phenanthroline ligands and between phenanthroline and pyridine-2,6-dicarboxyl-ate ligands.

Bis(?(3)-pyrimidine-4-carboxyl-ato)bis-(?(2)-pyrimidine-4-carboxyl-ato)tetra-kis-(aqua-lithium).

Project description:The asymmetric unit of the title compound, [Li(4)(C(5)H(3)N(2)O(2))(4)(H(2)O)(4)], contains two symmetry-independent Li(I) ions, two symmetry-independent ligands and two symmetry-independent coordinated water mol-ecules. They form a dinuclear unit in which the two Li(I) ions are bridged by two carboxyl-ate O atoms from the two ligands. Two dinuclear units related by an inversion centre form the tetra-meric mol-ecule. One of the Li(I) ions shows a distorted tetra-hedral coordination geometry, the other a distorted trigonal-bipyramidal environment. The tetra-mers are held together by hydrogen bonds in which coordinated water mol-ecules act as donors, and the carboxyl-ate O atoms act as acceptors. A hydrogen bond between coordinated water molecule as donor and a ring N atom as acceptor is also observed.

Project description:The asymmetric unit of the title compound, [Pd(C(6)H(4)NO(2))(4)]·2H(2)O, consists of a quarter of a neutral Pd(IV) complex and half of a solvent water mol-ecule. In the complex, the Pd(IV) ion is located on a fourfold inversion axis and eight-coordinated in a distorted dodeca-hedral environment by four N and four O atoms from four symmetry-related pyridine-2-carboxyl-ate (pic) anionic ligands. In the crystal, the water mol-ecule is involved in O-H?O hydrogen bonding, and weak inter-molecular C-H?O hydrogen bonds occur.

Hexaaqua-nickel(II) tetra-aqua-bis-(?-pyridine-2,6-dicarboxyl-ato)bis-(pyridine-2,6-dicarboxyl-ato)trinickelate(II) octa-hydrate.

Project description:The title compound, [Ni(H(2)O)(6)][Ni(3)(C(7)H(3)NO(4))(4)(H(2)O)(4)]·8H(2)O, was obtained by the reaction of nickel(II) nitrate hexa-hydrate with pyridine-2,6-dicarb-oxy-lic acid (pydcH(2)) and 1,10-phenanothroline (phen) in an aqueous solution. The latter ligand is not involved in formation of the title complex. There are three different Ni(II) atoms in the asymmetric unit, two of which are located on inversion centers, and thus the [Ni(H(2)O)(6)](2+) cation and the trinuclear {[Ni(pydc)(2)](2)-?-Ni(H(2)O)(4)}(2-) anion are centrosymmetric. All Ni(II) atoms exhibit an octa-hedral coordination geometry. Various inter-actions, including numerous O-H?O and C-H?O hydrogen bonds and C-O?? stacking of the pyridine and carboxyl-ate groups [3.570?(1), 3.758?(1) and 3.609?(1)?Å], are observed in the crystal structure.

Bis-(?-pyridine-2,3-dicarboxyl-ato)bis-[aqua-(3-carb-oxy-pyridine-2-carboxyl-ato)indium(III)] tetra-hydrate.

Project description:In the binuclear centrosymmetric title compound, [In(2)(C(7)H(3)NO(4))(2)(C(7)H(4)NO(4))(2)(H(2)O)(2)]·4H(2)O, which contains both pyridine-2,3-dicarboxyl-ate and 3-carb-oxy-pyridine-2-carboxyl-ate ligands, the In(III) atom is six-coordinated in a distorted octa-hedral geometry. One pyridine ligand is N,O-chelated while the other is N,O-chelated and at the same time bridging to the other via the second carboxyl group. In the crystal, an extensive O-H?O hydrogen-bonding network, involving the coordinated and lattice water mol-ecules and the carboxyl groups of the ligands, together with C-H?O and ?-? inter-actions [centroid-centroid distance = 3.793?(1)?Å], leads to the formation of a three-dimensional structure.

Tetra-kis[bis-(pyridin-2-yl)amine-κN (2)](nitrato-κO)silver(I).

Project description:In the title complex, [Ag(NO3)(C10H9N3)4], the nitrate ligand is found to be disordered over two sets of positions, with occupancy factors of 0.473 (5) and 0.527 (5). The Ag(I) ion is located in a square-pyramidal coordination environment formed by four N atoms from four bis-(pyridin-2-yl)amine ligands and one O atom from a nitrate ligand. Weak inter-actions between the Ag(I) ions and the nitrate anions acting in a monodentate mode [Ag⋯O = 2.791 (13) and 2.816 (9) Å for the major component of the nitrate ligand, and 2.865 (8) and 2.837 (8) Å for the minor component] link the complex mol-ecules into a chain along [001]. N-H⋯O hydrogen bonds are observed.

The Yb(III) atom is eight-coordinated in a distorted square-anti-prismatic geometry formed by two carboxyl-ate O atoms from two pda anions, and is N,O-chelated by one pda anion and four coordinated water mol-ecules. The pda anions bridge adjacent Yb and Cu cations, forming a three-dimensional polymeric structure. The crystal structure features extensive O-H?O hydrogen bonds. ?-? stacking is observed between parallel pyridine rings, the centroid-centroid distance being 3.843?(4)?Å.

Poly[[dodeca-aqua-bis-(?(3)-pyridine-2,6-dicarboxyl-ato)tetra-kis-(?(2)-pyridine-2,6-dicarboxyl-ato)tri-calciumdieuropium(III)] 10.5-hydrate].

Project description:In the title compound, {[Ca(3)Eu(2)(C(7)H(3)NO(4))(6)(H(2)O)(12)]·10.5H(2)O}(n), the Eu(III) ion is nine-coordinated by three tridentate pyridine-2,6-dicarboxyl-ate (PDA) ligands, forming a [Eu(PDA)(3)](3-) building block. The Ca(2+) ions adopt two types of coordination geometries. One Ca(2+) ion, lying on a twofold rotation axis, is eight-coordinated by four carboxyl-ate O atoms from four PDA ligands and four water mol-ecules, and the other two Ca(2+) ions, each lying on an inversion center, are six-coordinated by two carboxyl-ate O atoms from two PDA ligands and four water mol-ecules. The carboxyl-ate groups bridge the Eu(III) and Ca(2+) ions into a three-dimensional porous framework, with channels extending along [010] and [001] in which lattice water mol-ecules are located. Two of the lattice water mol-ecules are disordered over two sets of sites with equal occupancy and one water mol-ecule is 0.25-occupied. Numerous O-H?O hydrogen bonds involving the water mol-ecules and carboxyl-ate O atoms are present.
